A large manufacturing space with an average floor to ceiling height of 30 ft has a floor area of 5000 ft^2. The total infiltration rate for the space is estimated to be 1.5 air changes per hour. The inside design temperature and relative humidity are 72F and 50%. The pressure inside the conditioned space is 11.0 Psia. The building is located in Minneapolis, Minnesota. Determine the design heating load due to infiltration for this space for a 97.5% outdoor design conditions. In making your assumptions, you may take an outdoor humidity ration of 0.0001 lbH20/lbda and air specific volume under the given outdoor design conditions may be assumed as 12.2 ft^3/lbda.
